Examiner Peter K Mak has allowed 220 of 295 decided applications.
Peter K Mak maintains a pooled allowance rate of 75% across hundreds of decided applications in Technology Center 2400. His record spans 2 art units. The allowance rate ranges from 73% to 76% across these art units, reflecting variation in the decided application sets within each unit. This pooled figure represents the share of decided applications (allowed and abandoned combined) and does not include pending applications. The record aggregates results across multiple art-unit jurisdictions and describes past outcomes only.
A pooled record aggregates decided applications across multiple art units into a single overall allowance rate. The 75% figure reflects historical outcomes in applications already decided by this examiner across TC 2400. This aggregate statistic describes what has occurred and is not a prediction for any individual application. Range variation across art units reflects differences in the decided-application populations within each unit, not examiner performance variation per se.
These are aggregate statistics from this examiner's past public record — not predictions about any specific application. The per-art-unit figures below show how the record varies across art units. Our approach to patent prosecution →
Each section benchmarks this examiner against that art unit's average. Figures are this examiner's own public record within the art unit; the overall rate above pools them.
Grounds can co-occur, so the four don't sum to 100%. The art-unit figure is the unweighted mean across examiners in the art unit; §102 and §112 carry no art-unit benchmark.

Methodology. This page pools every art unit in which Examiner Peter K Mak has a public record within Technology Center 2400. Statistics are computed from publicly available USPTO records, refreshed on a recurring schedule. This page's data was last updated July 22, 2026. The overall allowance rate is total allowed divided by total decided applications (allowed plus abandoned) across all art units — not an average of the per-art-unit rates; pending applications are excluded. Figures are rounded for display. Pooled sample: 295 applications.
Rejection rates. Each §-rate is the share of this examiner's applications that drew at least one office-action rejection in which that statutory ground appears; applications with no rejection on record are excluded, and because grounds can co-occur the four do not sum to 100%. The art-unit figure beside each is the unweighted mean of the per-examiner rates across the art unit, published for §101 and §103 only. Beside the overall allowance rate we show a benchmark: for a single-art-unit examiner it is exactly that art unit's average, labeled “art-unit average”; for an examiner spanning several art units it is the “weighted peer average” — the per-art-unit averages, weighted by this examiner's application count in each — labeled distinctly because it is a blended figure, not any single art unit's average. Both are built from the same per-art-unit averages the panels show.

These statistics describe past examiner behavior and do not predict the outcome of any particular application. Past results do not guarantee future outcomes. Where this page compares an examiner's allowance rate to an art-unit average, that comparison is a factual description of the public record, not a characterization of any individual examiner's conduct or competence.
